Question

Solve $8x = - 72$

Answer 1

Hint: We can solve this question in many methods, we can either bring then 8 on right hand and divide it by $8$, we get the answer or we can divide by 8 on both sides to get an answer or we can use the multiples of $8$ and we can get the answer. There are a number of methods to solve this problem.

Complete answer:
Let’s consider the given question,
$8x = - 72$
$
  x = \dfrac{{ - 72}}{8} \\
  x = - 9 \\
 $
This is our required solution.

Additional Information:
 Let’s consider the given question
$8x = - 72$
Let’s bring $ - 72$ to the left-hand side we get,
$
  8x + 72 = 0 \\
  8(x + 9) = 0 \\
 $
The number $8$ vanishes and $(x + 9) = 0$,
$x = - 9$
This is our required solution.

Note: As we have many methods to solve this problem, so pick one of these methods which you think will be easy to solve. This problem is a basic one and you need to practice many problems so that you are able to solve it within a given time. When it comes to complex problems, it needs to be solved very quickly in order to crack all of the difficult problems.
